Final answer:
The demand for more profits was NOT instrumental in the abolition of slavery, unlike revolutionary movements, slave resistance, and Christian leadership, with moral suasion being a key strategy among abolitionists.
Step-by-step explanation:
Among the options given, the one that was NOT instrumental in the abolition of slavery was A. demand for more profits. Instead, revolutionary movements, slave resistance, and Christian leadership played significant roles in the abolitionist movement. Revolutionary movements provided ideological frameworks that emphasized equality and human rights. Slave resistance, through uprisings and rebellions, highlighted the injustices and inhumanity of slavery and made its maintenance increasingly untenable. Christian leadership, particularly from evangelical abolitionists, bolstered the movement by appealing to moral and religious sentiments for immediate emancipation, a strategy known as "moral suasion". These forces culminated in various forms of activism, including William Lloyd Garrison's immediatism and strategies that influenced political spheres, contributing to the ultimate end of slavery in the United States.
